Tendon defect reconstruction is a challenging procedure that can be complicated by tendon retraction or tendon gap increase after debridement of interposed scar tissue. Although application of tendon autografts from dispensable tendons is considered the gold standard for bridging the gap, donor-site morbidity cannot be ignored. We use a local sliding tendon autograft which can avoid distant graft harvesting and it is adaptable across all tendon zones for reconstruction of tendon defects. A reverse l-type longitudinal incision of the same length with the measured final gap is made at the midsubstance of the proximal tendon stump and the created intercalary tendon segment is transferred distally to bridge the gap, providing an "elongated" proximal stump of the required length. The Elongation Rail Technique has been applied successfully in four patients with flexor tendon defects with favorable results and functional outcome at 6 months follow-up according to Strickland and Glogovac criteria.
肌腱缺损重建是一项具有挑战性的手术，在清除中间瘢痕组织后，可能会因肌腱回缩或肌腱间隙增大而变得复杂。尽管应用来自非必需肌腱的自体肌腱被认为是填补间隙的金标准，但供区并发症不容忽视。我们使用局部滑动自体肌腱，它可以避免从远处获取移植物，并且适用于所有肌腱区域以重建肌腱缺损。在近端肌腱残端的中间部分做一个与测量的最终间隙长度相同的反向L型纵向切口，将形成的中间肌腱段向远端转移以填补间隙，从而提供所需长度的“延长”近端残端。根据斯特里克兰和格洛戈瓦茨标准，延长轨道技术已成功应用于4例屈肌腱缺损患者，随访6个月时效果良好，功能结果满意。
